Solution
No, it is not possible that productivity of a natural community remain constant over a certain time period.
This is because
- The natural habitat is never maintained in real.
- Abundant resources are never available, they are always in short supply or just enough.
- Environment conditions for survival and reproduction are continuously changing.
